form openings to receive the weft-wires, which may be inserted by handor automatically, the especial object of the invention being to providean efficient and durable machine of this class capable of operating at asatisfactory speed. In securing this result I employ a pair ofcrimping-rolls provided with'teeth arranged to crimp all the warp-wiresalternately in opposite directionsand to crimp the adjacent warp-wiresin opposite directions, so that the weft-wires inserted when the shed isopened willbe held in the closed loops formed by the upward and downwardcrimps in adjacent warp-wires when the shed is closed. connection withthese crimping rolls and suitable means for raising and lowering thewarpwires alternately to open and close the shed my complete machine inits preferred form includes guiding-fingers between which the warp-wirespass, which fingers are formed so as to provide guides for theweft-wires, insure ing their proper position when inserted, theseguiding -'fingers being withdrawn when the weft-wire has been insertedand the fabric is to be advanced.

In addition to the above features of the crimping-rolls and theweft-wire guides the invention includes various combinations of' partsand features of construction in an organized machine of the generalclass above described. E

For a full understanding of the invention a detailed description of aconstruction embodying all the features of the same in their preferredform will now be given, in connection with theaccompanyingdrawings,'formingpart of this. specification, and thefeatures forming the invention will then be specifically pointed out inthe claims.

In the drawings, Figure 1 is a side elevation of the machine. Fig. 2 isa plan view of Fig. 1. Fig 3 is a vertical sectional view taken on theline 3 3 of Figs. 2 and 4. Fig. 4 is a sectional end view taken on line4: 4 of Fig. 1. forming fingers.

Referring to said drawings, A A are the side frames, in which is mounteda drivingshaft B, which may be driven from any suitable source of power.Mounted in the frames A A above the driving-shaftB is a cam-shaft C,driven from the shaft B by gears D E. The warp-wires 00 are led from aseries of spools F, mounted on the shaft 10, journaled insupports 11,secured to the frames A A of the machine, over a roll, as 12, thencethrough guide-grooves 13, formed in a bar 14, secured to the side framesof the machine. The grooves 13 guide the warp-wires to the pair Fig. 5is a detail view of the shed of crimping rolls G H, arranged one abovethe other, the crimping-rolls G H in the form shown consisting of anumber of disks 15 16.

-The disks 15 16 are provided with conicalshaped teeth 1 2,respectively, meshing one with the other, thedis'ks being secured toshafts 17 18, journaled in brackets 21, secured to the frames A A. i g

The journal-boxes19 20 are adjustable one to the other by means ofsuitable adjusting screws 22 for the purpose of giving a greater or lesscrimp to the wires while the wire is being drawn between the saidcrimping-rolls by suitable winding-up devices, as hereinafter described.It is necessary that. the crimps in each alternate wire should bear aproper relation one to the otherthat is, the higher portion of the crimpin one wire should be opposite the lower portion of the crimp in thealternate wire or wire next it. To provide for this, the teeth 1 2 ofeach adjacent disk 15 16 are staggered that is, a tooth 1 of one of thedisks 15 will be positioned so as to be in line with the space betweentwo of the'teeth 1 of the next or adjacent disk 15 the teeth 2 of thedisks 16 being arranged in a similar manner, as shown in Figs. 2 and 3.

The crimping-rolls G H may be rotated in any suitable manner, the meansfor rotating said crimping-rolls as shown in the drawings consisting ofa ratchet-wheel 23, secured to one end of the shaft 18 of thecrimping-disks 16, the ratchet 23 being engaged by a springpressed pawl24, pivoted in the upper end of a two-armed lever 25 26, loosely mountedon the shaft 18, the lower arm 26 of said lever being connected by alink 27 to a cam-lever 28, pivoted to the frame of the machine at 29 andcarrying a roll 30, which engages a camgroove 31 in a cam-disk 32,carried by the shaft C, the cam-gr0ove 31 being so formed as to actuatethe lever 28, and thereby the pawl 24, twice for every revolution of theshaft C, the amount of rotation given the crimping-disks 16 beingadjustable by means of holes 33 in the arm 26 of the pawl-lever andholes 34 in the cam-lever 28, which are entered by the pins 35 36 of thelink 27. The upper crimping-disks 15 are driven from the shaft 18 bymeans of a gear 37, secured to shaft 17, and gear 38, secured to theshaft 18 of the crimping-disks 15 16, respectively.

The warp-wires w as they pass from between the crimping-rolls G H areengaged by shedforming devices, from which they pass to suitable guideswhere the weft or cross wires 1 are inserted. The shed-forming devicesconsist of two bars 40 41, mounted in guideways in brackets 42, securedto the frames of the machine. The bars 40 41 carry upwardly-projectingfingers 43 44, formed integral with or otherwise secured to the bars 4041, the lingers 43 44 being provided with openings 45 46, through whichare passed the crimped wires .12, (see Fig.3,) the bars 4041 beingraised and lowered alternately to form the shed and allow of theinsertion of the cross-wires y in the following manner: The lower edgesof the bars 40 41 have formed integral or otherwise secured to themdownWardlyprojecting arms 47 48, to which are connected the ends ofcam-levers 49 50, fulcrumed on the bar 51 carried by brackets 52,secured to the frames of the machine. The

cam-levers 49 carry rolls 53 54, which engage cam-grooves 55 56, formedin either side of cam-disks 57 58, carried by the shaft C. Thecam-grooves 55 56 are similar in form and adapted to actuate thecam-levers 49 50 to raise and lower the bars 40 41 alternately once forevery revolution of the camshaft C. The bar 40 as shown in Fig. 3 is inits raised position and the bar 41 is in its lower position, therebyseparating the alternate warp-wires m as is usual in this class ofmachines, thus forming the shed through which is passed, by hand orotherwise, the

cross or weft wire y.

As the fabric in some cases will be of con 'siderable width, it isdesirable to provide means for guiding the weft-wire y with certainty inrelation to the warp-wires as the weft-wire is inserted. To accomplishthis, a guideway 3 is provided in the upper part of a vertically-slidingbar 60, adjacent to the shedforming devices, the guideway 3 being formedin lingers 4, integral with or secured to the bar 60. The spaces betweenthe lingers 4 form slots or guideways 5, (see Fig. 4,) running at rightangles to the guideways 3, and these guideways 5 act to guide thewarp-wires a: as the bars 40 41 move the said warp-wires vertically. Theguideways 3 in the lingers 4 are flared or bell-shaped at the end atwhich the weft-wire 1 enters, as shown at 6, (see Figs. 2 and 4,)thereby facilitating the entrance of the weft-wire into the guideways 3.Above the bar 60 a stationary bar 66 is mounted in the frames A A, thisbar having fingers 7 cooperating with the lingers 4 of the bar 60 toclose the guideway 3 at the top when the bar 60 is in its upperposition. They also act to guide the warp-wires when the warp-wires aremoved upward, as before explained.

The weft-wire is inserted while the bar 60 is in its upper position, andafter the weftwire has been inserted the bar 60 is lowered to withdrawthe lingers 4 from the wires, so as to permit the fabric and warp-wiresto move forward, when the bar 60 will be raised into its former positionfor the reception of another weftwire. The means shown for raising andlowering the bar 60 are as follows: The bar 60 has adownwardly-cxtending arm 61, to which is connected one end of a camlever62, the other end of said lever being fulcrumed on the bar 51. The lever62 carries a roll 63, which engages a cam-groove 64, formed in acam-disk 65, the cam-groove being so timed as to actuate the bar 60twice for every revolution of the shaft 0, the bar 60 be ing suitablyguided in the brackets 42.

The fabric is drawn forward after a weftwire has been inserted bytoothed feeding disks or rolls 68, acting to aid the pushing action ofthe crimping-disks 15 16. The disks 68 are secured to a shaft 69,mounted in brackets 70 on the frames A A of the machine, and the fabricis shown as taken up, as usual, on a reel 1 on shaft J. The shafts 69and J may be driven in any suitable manner to draw olf and reel up theproper amount of fabric as the warp-wires are released from thecrimping-rolls, the means shown being slip-belts 71 72 and pulleys 7374, the belt 71 being driven by pulley 75 on the cam-shaft C.

If the wires forming the fabric are of large size and it is notdesirable to reel it, the fabric may be fed or drawn along and cut intosheets of the desired lengths, the crimpingrolls G H allowing thefeeding-disks 68 to draw off the completed fabric.

A general description of the operation of the machine thus organized isas follows: The warp-wires are drawn from the spools F by thecrimping-rolls G H, the crimping-rolls being rotated to draw off theproper amount of wire 00 by means of the ratchet 23 and pawl 24, whichare actuated from the cam 31 and levers 25 and 28. As the crimping-rollsare as to place the higher portion of the crimp formed in one wireopposite the lower portion formed in the adjacent wire. The crimpedwires pass to the shed-forming devices, wh ere they are separated bymeans of the shed-forming bars 40 41 at the proper time by meansof thelevers 49 5O andcams 56. From the bars 40 41 the wires pass through theguidingfingers 4 of the bar 60, where the weft or cross wires y areinserted. The shed-forming bars 40 41 now reverse their position--thatis, the bar 40 will be lowered from the position shown in Fig. 3 and thebar 41 raised, wrapping or binding-the warp-wires around thecross-wires.- While this movement of the bars 40 41'is taking place thebar 60, carrying the fingers 4 and guideways 3, will be lowered, so asto allow a free passage of the fabric, by means of the lever 62 and cam64, when the crimping-rolls G H will again be actuated to feed and crimpthe wires and at the same time the drawing-off disks 68 and the reel Irotated by means of the slip-belts 71 72to draw 0H and wind up an amountof fabric equal to the feed of the crimping-rolls G H. The bar will nowbe raised again to the position shown in Fig. 3, when another weft-wiremay be inserted and the operation of the crimping-disks and shed-formingdevices be repeated.

-The weft-wires y are shown as put in at every fourth crimp; but it willbe understood that this will be varied according to the fabric required,and a weft-wire may be put into each crimp or as often as desired, theattendant simply inserting a weft-wire when the shed is opened and thebar 60 raised, or not,

according to the spacing of the weft-wires desired. I
